Selena Gomez Rings In 21st Birthday With New Music Video: Watch Now!

Gomez and her friends celebrate the big day with a good old-fashioned warehouse party in the new clip.

Selena Gomez said she wanted to throw "a huge party" for her 21st birthday. And that's exactly what she did in the early hours of Monday (July 22), the day of her actual birthday, when she dropped a celebratory clip for her Stars Dance cut "Birthday."

The gritty clip follows Selena and her pals as they party in a graffiti-filled warehouse, mirroring the lyrics of the up-tempo jam where she sings, "Blow your dreams away with me."

The video is the second official release off Stars Dance, following up "Come & Get It." Whereas the "Come & Get It" clip was a production that included several costume changes and choreographed dance routines, this video's more laid-back vibe seems to capture Gomez on a typical night with her friends.

On Saturday, two days before her own big day, Gomez and friends like Lily Collins gathered at the Roosevelt Hotel for a 20s-themed fete in honor of another birthday girl, Julianne Hough, according to a report. Gomez not only wore a flapper-inspired LBD, she accessorized it with some devil horns. She did celebrate her birthday in the early hours of Monday morning — with tacos! She wrote, "My cake was... Jack n the box tacos... Yes." #turnupNOW indeed!

Gomez will keep the party going this week when she drops her new album, Stars Dance, on Tuesday. And, she's made it clear to MTV News earlier this summer what her primary goal is.

"To be honest, most of the record actually speeds up once I release [the first single] 'Come & Get It'," she said. "The rest of the record, I've never taken this long to work on a record before. ... It was really fun for me to have more of a creative control and more of a say. I want it to be a mixture of everything I'm obsessed with. I love to dance and I love to make people dance."
